Two men and one woman are charged with aggravated kidnapping, police said. The men also are charged with aggravated robbery.

Police said the men broke into a home in Conroe and abducted the man. His 12-year-old son called police, who called the FBI for assistance.

The FBI followed cellphone signals to a motel near Houston, where two suspects — both of them men — were found. The suspects directed FBI agents and police officers to a house where another suspect — a woman — was located along with the man who was being held captive. Other people, including children, also were at the home, according to authorities.
